IMPORTANT NOTICE
1. When using the LSI for new models, verify the safety including the long-term reliability for each product.
2. When the application system is designed by using this LSI, please confirm the notes in this book.
Please read the notes to descriptions and the usage notes in the book.
3. This LSI is intended to be used for general electronic equipment.
Consult our sales staff in advance for information on the following applications: Special applications in which exceptional
quality and reliability are required, or if the failure or malfunction of this LSI may directly jeopardize life or harm the human
body.
Any applications other than the standard applications intended.
(1) Space appliance (such as artificial satellite, and rocket)
(2) Traffic control equipment (such as for automobile, airplane, train, and ship)
(3) Medical equipment for life support
(4) Submarine transponder
(5) Control equipment for power plant
(6) Disaster prevention and security device
(7) Weapon
(8) Others : Applications of which reliability equivalent to (1) to (7) is required
Our company shall not be held responsible for any damage incurred as a result of or in connection with the LSI being used for
any special application, unless our company agrees to the use of such special application.
4. This LSI is neither designed nor intended for use in automotive applications or environments unless the specific product is
designated by our company as compliant with the ISO/TS 16949 requirements.
Our company shall not be held responsible for any damage incurred by customers or any third party as a result of or in
connection with the LSI being used in automotive application, unless our company agrees to such application in this book.
5. Please use this product in compliance with all applicable laws and regulations that regulate the inclusion or use of controlled
substances, including without limitation, the EU RoHS Directive. Our company shall not be held responsible for any damage
incurred as a result of our LSI being used by our customers, not complying with the applicable laws and regulations.
6. Pay attention to the direction of LSI. When mounting it in the wrong direction onto the PCB (printed-circuit-board), it might emit
smoke or ignite.
7. Pay attention in the PCB (printed-circuit-board) pattern layout in order to prevent damage due to short circuit between pins. In
addition, refer to the Pin Description for the pin configuration.
8. Perform visual inspection on the PCB before applying power, otherwise damage might happen due to problems such as
solder-bridge between the pins of the semiconductor device. Also, perform full technical verification on the assembly quality,
because the same damage possibly can happen due to conductive substances, such as solder ball, that adhere to the LSI
during transportation.
9. Take notice in the use of this product that it might be damaged or occasionally emit smoke when an abnormal state occurs
such as output pin-VCC short (Power supply fault), output pin-GND short (Ground fault), or output-to-output-pin short (load
short). Safety measures such as installation of fuses are recommended because the extent of the above-mentioned damage
and smoke emission will depend on the current capability of the power supply.
10. The protection circuit is for maintaining safety against abnormal operation. Therefore, the protection circuit should not work
during normal operation.
Especially for the thermal protection circuit, if the area of safe operation or the absolute maximum rating is momentarily
exceeded due to output pin to VCC short (Power supply fault), or output pin to GND short (Ground fault), the LSI might be
damaged before the thermal protection circuit could operate.
11. Unless specified in the product specifications, make sure that negative voltage or excessive voltage are not applied to the
pins because the device might be damaged, which could happen due to negative voltage or excessive voltage generated
during the ON and OFF timing when the inductive load of a motor coil or actuator coils of optical pick-up is being driven.
12. Verify the risks which might be caused by the malfunctions of external components.
13. Due to the unshielded structure of this LSI, functions and characteristics of the product cannot be guaranteed under the
exposure of light. During normal operation or even under testing condition, please ensure that the LSI is not exposed to light.
14. Please ensure that your design does not have metal shield parts touching the chip surface as the surface potential is GND
voltage.
